16-Week REVEL Big Bear Marathon Training Plan

Big Bear, CANovember 8, 2026

Start around July 19, 2026. The calendar below gives each phase a real date, then the course guidance shows where to make the build specific to REVEL Big Bear Marathon.

REVEL Big Bear starts at 6,630 feet near Sugarloaf Mountain and finishes 5,081 feet lower at Redlands Sports Park. That's close to a vertical mile of descent inside one race, and roughly 4,200 feet of it comes after mile 9, an average grade near 4.7% across the final seventeen miles.

Does this window fit your starting point?

Use this window when you have a running base and want several weeks before the hardest marathon-specific work begins. The extra month over a 12-week plan creates more room for gradual long-run growth and recovery.

  • You run consistently enough that week one is a continuation, not a restart.
  • You want a distinct foundation phase before the biggest long runs.
  • You can protect your planned run days for roughly four months.
  • Your race date leaves the full window without forcing skipped weeks.

The 16-week REVEL Big Bear Marathon calendar

These dates define the job of each phase. Your current mileage, recent longest run, experience, goal, and available days still decide the actual workouts inside them.

Foundation

Weeks 1–4

Jul 20, 2026–Aug 16, 2026

Establish repeatable weeks, keep most running easy, and begin extending the long run without forcing the pace.

Build

Weeks 5–10

Aug 17, 2026–Sep 27, 2026

Increase the weekly load, preserve step-back weeks, and introduce the terrain and effort the race will require.

Peak

Weeks 11–13

Sep 28, 2026–Oct 18, 2026

Complete the biggest race-specific weeks and use long runs to lock in fueling, pacing, and equipment.

Taper

Weeks 14–16

Oct 19, 2026–Nov 8, 2026

Bring volume down while keeping the weekly rhythm familiar. Training is finished before race week begins.

Make the window specific to REVEL Big Bear Marathon.

Use the first month to establish consistency, then make long runs progressively more specific to the race's terrain and conditions. The course rehearsal should grow with the plan, not appear all at once in peak week.

How to train for REVEL Big Bear

Train for REVEL Big Bear by building eccentric quad durability over months rather than weeks. A 5,081 foot descent damages muscle in a way flat running never does, and the adaptation is slow. Show up aerobically fit but downhill-untrained and your quads will fail somewhere around mile 18 to 20, turning the last six miles into a walk.

Start downhill repeats twelve weeks out at the latest, once a week, on a grade in the 4% to 6% range if you can find one. Begin with a handful of short repeats and build the volume gradually, because this is the one stimulus where too much too early produces injury instead of fitness. Two to three weeks out, do a long run with a sustained descent that mimics the real thing, then take a proper recovery week.

Form here is a technique problem, not a strength problem. Short quick steps, cadence high, foot landing under you rather than out in front. Every time you reach forward and land ahead of your center of mass on a descent you brake, and braking is what tears the tissue. Practice until it's automatic, because at mile 22 you won't be making conscious decisions.

Add strength work that loads the quads eccentrically: slow-lowering split squats, step-downs, single leg work. And run your last long run in the exact shoes and socks you'll race in. On a course that drops nearly a mile, feet slide forward, and lost toenails are the standard price for guessing at fit.

Boston qualifying note. The Boston Marathon adds 10 minutes to qualifying times run on courses that drop this much, starting with 2027 registration, so a time here counts as 10 minutes slower than the clock.

Start-line temperature is not listed for this race. The course finishes thousands of feet below where it starts, so the weather recorded in the finish city does not describe the start line.

16-week REVEL Big Bear Marathon plan questions, answered.

When should I start a 16-week REVEL Big Bear Marathon plan?

The 2026 REVEL Big Bear Marathon is scheduled for November 8, 2026, so the 16-week window opens around July 19, 2026. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.

Is a 16-week plan long enough for the REVEL Big Bear Marathon?

Use this window when you have a running base and want several weeks before the hardest marathon-specific work begins. The extra month over a 12-week plan creates more room for gradual long-run growth and recovery. The course does not change the opening load you can handle, so choose from your current mileage and recent longest run before adding race-specific terrain.

How should I prepare for the REVEL Big Bear Marathon course in 16 weeks?

Use the first month to establish consistency, then make long runs progressively more specific to the race's terrain and conditions. The course rehearsal should grow with the plan, not appear all at once in peak week. Train for REVEL Big Bear by building eccentric quad durability over months rather than weeks. A 5,081 foot descent damages muscle in a way flat running never does, and the adaptation is slow. Show up aerobically fit but downhill-untrained and your quads will fail somewhere around mile 18 to 20, turning the last six miles into a walk.

What if the 16-week REVEL Big Bear Marathon window has already started?

Do not double weeks or cram missed mileage into the remaining calendar. Use your current mileage, recent longest run, experience, goal, and available days to choose a plan that can enter at an appropriate point while preserving the taper.

How much does REVEL Big Bear drop?

5,081 feet net, from 6,630 feet near Sugarloaf Mountain down to Redlands, California. About 4,200 feet of that comes after mile 9, an average grade near 4.7% across the final seventeen miles, and the last three miles alone drop 443 feet. There's only about 330 feet of climbing in the whole race.

Is REVEL Big Bear a good Boston qualifier?

It has an unusually high qualifying rate: 40.5% of finishers ran a Boston qualifying time in 2023. But the BAA's net downhill index applies to courses this steep, and for Boston registration from 2027 onward a time here is treated as ten minutes slower than the clock. Factor that into your margin.
